Locust安装失败：Running setup.py install for geventhttpclient ... error

最近想学习Locust性能测试，没想到卡在了安装上。
根据官方指导文档，执行pip install locust，报错信息如下所示：

解决方法，我认为有两个：
一是、根据提示去安装Microsoft Visual C++ 14.0，但是这个方法消耗的时间和空间都非常的高，大家可以量力而行；
第二种方法就是安装最新（发布前）的locust，

pip install -U setuptools
pip install -U --pre locustio

安装成功
